ATP ADENOSINE TRIPHOSPHATE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
ATP is a cell’s main form of energy “currency.” Which of the following comprises an ATP molecule?
A
adenine, the sugar ribose, and three phosphate groups
B
adenine, the sugar deoxyribose, and two phosphate groups
C
a nitrogenous base, a phosphate group, and the sugar ribose
D
a complex molecule of amino acids
Explanation: 

Detailed explanation-1: -ATP – Adenosine triphosphate is called the energy currency of the cell. It is the organic compound composed of the phosphate groups, adenine, and the sugar ribose. These molecules provide energy for various biochemical processes in the body. Therefore, it is called “Energy Currency of the Cell”.

Detailed explanation-2: -The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

Detailed explanation-3: -(a) Chemical structure of adenosine triphosphate (ATP); (b) The ATP molecule is composed of an adenosine ring and a ribose sugar with three phosphate groups. From the high energy bonds among the phosphate group, ATP is produced.

Detailed explanation-4: -ATP or adenosine triphosphate is composed of one adenine molecule, a ribose sugar and three phosphate groups. Its chemical formula is C10H16N5O13P3. ADP or adenosine diphosphate is composed of one adenine molecule, a ribose sugar and two phosphate groups.

Detailed explanation-5: -ATP is adenosine triphosphate. It consists of a nitrogenous compound called adenine, a pentose sugar called ribose and 3 phosphate molecules.
